Hello,

I also noticed the same problem and agree that the search path belongs
in the vulkan-loader package:

I tested it with
--8<---------------cut here---------------start------------->8---
guix shell -C vulkan-tools vulkan-loader mesa --no-grafts -- vulkaninfo
--8<---------------cut here---------------end--------------->8---
which works with the patch applied. As documented in [1], vulkan-loader
still needs to be part of the profile for the search path to take effect.

Cheers,
David
